` V:To all whom rmay concern: i

Be it known that I, IRA C. HAVENs, a citi- 4;zen` ofthe United States, residing at the city andcounty of Kalamazoo, State of Michigan, have `invented certainl new l Improvements Motor-Vehicles,

andl useful ,in Auxiliary Propellers for of which the' following is a specification.

This invention `relates to improvements in auxiliary `propellers for motor vehicles.

The-.main objectsofthis invention are:

First, `to provide an improved auxiliary propeller for motor vehicles which may be y 4 used tosupplement the regular driving and traction means ofthe vehicle and without additionaldoad upon the motor when the :propeller'is infuse..`

l .Second, to provide an improved supplemeans for moniental driving or propellin vantages which tor vehicles having these a lis; comparatively simple and easyofcontrol.

Further objects, and objects relating to structural details, will definitely appear 'bythe devices and means described in the f following specification.

through one of the control valves on a line corresponding to line 7 -7 of Fig. I.

Fig. VIII is a detail section on a line corchassis of amotor vehicle, and I here use the term as including the running gear" frame, wheels, axles, motor and transmission. As the details of these parts form no part of my invention they are not illustrated or described herein.

I pivotally mount a propeller cylinder 2 on the hanger 3 at 3. The hanger 3 depends from the chassis frame and is provided with a brace 4. Within the cylinder 2 is ya piston orplunger 5 to which the propeller or pusher being arranged through the head 7 of the cylinder which is provided with suitable packings. In the structure illustrated these bars are formed of outer tubular members 8 and rods 9, the rods being arranged through the tubular members and constituting tie members. On the rearends of the bars 6 is a shoe 10, the same being reinforced with a cross member 11 on the rods.

This provision of the double piston rods not only provides a structure which is well adapted to receive and sustain the loads and stresses to which they are subjected and to bars 6 are secured, the bars relieve the piston of undue stresses, but also pressure is connected by the pipe 13 to an engine driven pump 14 and by a branch 15 to the hand pump 16. This provides means for charging the storage tank through the engine under normal ruiming conditions if desired or where thatis not practical the pressure may be supplied through the hand pump.

Y The propeller cylinder 2 is connected by the pipes 17 and 18 to the ends of the control valve member 19, the connection 17 lead-` ing to the front end of the cylinder' and the connection 18 to therear end thereoit'. These connections have flexible portions, as 20, therein permitting the swinging of the cylinder on its supporting pivot 3. y

The sleeve portion 21 is slide-ble on the member 19 and is connected by the inlet pipe 22 to the storage tank 12, the connection 22 having a slip coupling 23 therein permitting the reciprocating movement of the valve sleeve 21. The valve member 19 has a central partition 24 with ports 25 at each side thereof. The valve al has a port 26 with which the cnnec'tion 22 communicates so that as the valve is shifted the ports 25 are .alternately connected with the storagetank, thus alternately connecting the opposed ends of the cylinder therewith and with the exhaust.

The vexliaustpassages 27 are formed longitudinally the packing glands 28 of the valve. Wlien in the central or neutral position the valve lis `closed and both ends of the Cylinder are connected to the exhaust passages,-see Fig. VII. The valve is actuated from the lever 29 positiond so as to be in convenient reach of the operator, vthe lever Vbeing connected to the valve by means of the link 30.

rllora-ilse or lower the propellercylinder to and' vfrein its operative position I providev a cntrol or lifting cylinder 3l pivotally inounted at 32 on the chassis and provided with a pstong, the piston rod 34 of which is piytallypoiilieetecl t the propeller cylinder at 35. lliis cylinder is eontrelled by the valve 1 9 which is preferably a duplicate of the valve '19 described, the valve i9 being controlled from the lever 29 disposed at the side f the lever 29. The valye is connected t, the cylinder 31 through the connections 17 and 18 substantially as described for the prpvpeller cylinder connection.

hen it is desired to actuate the propeller the lever 29 is shifted to lower kthe Apropeller cylinder by admitting air to the upper end of the cylinder 31 and then actuating the pro` eller or pusher through the adjusting of the ever 29.

My improved propeller is entirely independent of the regular driving means for the motor so that in the event of emergencies rendering the use ol the propeller desirable the motor and regular driving means are not further taxed and in tlie event or the :motor econiin'g inoperative the auxiliary propeller n iay be resorted to for temporary propulsion.

I have illustrated and described my improvements in but one embodiment as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be esirey Having thus described my inventiom `said propeller.
